TIOAT QE BaQ tm. NEW. Years. a QQa QRAT Q or YQEJSJ @I'PE'WIEQE ma aw WW My present invention relatesto pile Wires, and has particularreference to the blade holder which is asso ia ed therewith.

The use of pile wire cutters inth'e manufacturebfpile fabrics is besetwith many difficulties. One of thesehas' its origin in'the necessity fort nse-any replenishing the.

been placed into use.

Vhe'reIha've used blade holders which comprise channel portions forreceiving the blades, I have'fo'und it desirable to plugor blockportions of the channel forthe purpose of frnii ng a recess into whichan end of the blalemay be inserted; It'is anobjeet of the present"invention to" accomplish "this 'pur poseby means of a constructionwhich 1st: one time" inexpensive, simpl and eflicient.

In accordance with this object of'thein f) ventio n,I have "found itextremely satisfactory to produce this result by the insertion ot aplug, suitably configured, 'intoan end portion of the channel.Moreparticularly, the plug is so arranged andconstructed as to 4 i 4 iJ. l'OVlClG an overhan un end DOIUOII or wall beneath which an endf'ottheciitting blade may beinserted. 'fl

Another one of the difficulties encountered in the use of pile ires isbased upon the vdill'erent requirements of di fierent looms or mills.More particularly, in certain-cases a pile Wire of a certain height isusedor required, and in other cases, pile Wires having a differentheight are necessary. It has therefore been necessary heretofore to pro}vide bladeholders, eitheras attachments for the pile wires or asintegral parts thereof, in varying sizes; and more particularly, it hasbeen necessary to provide bladefliolders of different heights. Inasmuchas the cutting blade must project out of the blade holder. by aproperpredetermined amount, it has been necessary to provide not onlyholders of difierent heights, but also blades of :lii .terent sizes; Thereason 'for thisvvill carriers.

distance from the blade holder.

'It'is an ob" ct of the 'p esent invention to overcome this difficultyand to" permit the utilization of a standardized blade With all heightsof blade lioldeis. "Accordingly, a feature of theinvention lies in proiding means for rendering each of a seriesof blade holders available foruse witha stand ard blade, thereby increasing the efficiency of use, andefl'ecting'grea't economies in the manufacture of blade iolders. Q

reas n 15.- aaanan. or New air, s Qe o LOX stat seasonewilhstillbeenabled to project' paper In accordance with the embodiment herein 7disclosed, I provide an insertorplug which is capable of beingassociated with the blade holder so as to reduce the effective depth ofthe channel therein. 'Moreparticul'arly,

I provide a series of these plugs, tlie plugs varying in sizeinaccordance \vitli the varying heights of b lade holdeI-s, so that anyselected blade holder may be standardized by the association therewithof aproperly selected insert a l For the attainment of the foregoingobjects and such otherobjects'as may hereinafter appear or be pointedout, I ave illustrated 'lny invention in ing draWings-in whichf v V Fig.l isa side elevation of a pile wire blade holder ofrelatively smallheight, having associated therewith a blade which may, for illustrativepurposes, be considered standard; i Fig; 2 is a similar view of theblade un associated with holder; I Fig. 3 is a perspective View ofabladeholder having a relatively greater height,

"the accompany and having the standard blade associated therewith inaccordance "with'the present 11, the purpose of Which will be Well-knownto those skilled in the art. I The blade holder shown is of the typewhich is constructed of a substantially flat blank doubled-over along alongitudinal line 12 to form a U- shaped blade, receivng channel 13.

The blade which I prefer to use-is of the flexible wafer type having abottom'edge 1d,

a cutting edge 15. disposed atan angle to the edge 14, and aforward...cl which v the blade holder of Fig. 1. This bladeholdcompletes a generally triangul ar figure. Theblade is associatedwith a holder by positioning its rearjend-ror foot 17, under anoverhanging wall o'f the character hereinbefore referrec tc. The otherend 16 is constructed manner which permits 'coereof with a suitable tab18 provided on the spoon portion 11. More par ticularly, this tab 18 isstruck up out of the spoon portion '11 into thepath of the chair nel,and it comprises a transverse edge 19, and upper and lower edges 20 and21 respectively, each of the edges 19,20, and 21 having been formed bycutting proper slits through the spoon portion 11. For a pose presentlyto be understood, the slit20 is preferably made shorter than the slit21. For proper co-operation with the tab 18, the end 16 of-the blade isconstructed with. a cut-out portion which provides an end edge 22parallel to the edge 16 but offset with respect thereto, and aconnecting edge 23 substantially parallel to the edge 1%. After the foot17 of the blade has been properly positioned, the entire blade is flexedso that the end 16 will spring into place beneath the tab 18. o Moreparticularly, the edge 22 willbe caught by the end of the slit 20,

while the edge will encounter the edge 21 and prevent upward movement ofthe blade after it has been positioned.

I shall now describe the construction which permits engagement of thefoot 17 ofthe blade. The general purpose is to provide an overhangingwall 24 (Fig. 1) be-v neath which the foot 17 may rest.

channel upwardly and forwardly to the open end of the channel. In Fig. 3I have shown I provide a wedge-shaped insert 25 having an under-edge 25which may be said to be beveled. More specifically, the under-edge 26 isarranged at an angle to the axis of the channel. Thereby, only a portionof the channel is eifectively blocked by the wedge This portion is theouter portion of the channel, the inner portion being unblocked by theinsert and constituting an undercut.

recess. The member 25 may be secured in position by any suitable means.as by welding, soldering, or otherwise. ,VVhere a mem berof this type isused, I prefer to shape its outer edge in a manner which will make itconform to the upper edge of the blade holder. The inclination of theunder-edge purer comprises a similar spoon portion 11, tab 18, andchannel portion 13. It will beobserved, however, that the depth of the.CllaIl-r nel is,.in this case, much greater than that of Fig. 1. is toogreat, with respect to the blade depth, to permit proper positioning ofthe blade within the channel, so as to have the proper In fact, thedepth ofthe channel amount of projection out of the channel.

For the purpose of rendering this blade holder available for use withthe standardized blade, I provide. a plugging member 33 in the form of astrip, this member be ing insertable into the channel 13 so as toprovide a raised bottom therefor. proper selection of insert 33,vthe newbottom may be provided at a'predetermined raised point with respect tothe bottom of the holder. The blade may be made to rest upon thissubstitute bottom in lieu of the original channel bottom. The insert 33may By the.

or merely by frictional engagementwithin the channel. It will beunderstood that its application need not necessarily afiect the.

overhanging wall construction hereinabove described. The latter may beprovided uponthe basis of the newly formed bottom. That .is, where awedge member is employed, it

may be preferably associated within the channel so as to extend only tothe insert This, however, isnot essential, as will be understood. I I

It will be obvious that variousfchanges in the details herein describedand illustrated for the purpose of explaining the nature ofv myinvention maybe made by those skilled in the art without departing fromthe spirit and scope of the invention as expressed in the appendedclaims. It is therefore intended that these details be interpreted asillustrative, and not in a limit ing sense.

- Having thus described my invention and illustrated its use, what Iclaim as new and desire to secure by Letters Patent is 1. A pile wirecutter comprising -a U-shaped blade-receiving channel, a remov;

able blade for insertion thereinto, and a plug carried entirely withinthe channel at one end thereof and configured to provide an undercutrecess within which one end of the blade may be made to rest. v

2. A pile wire cutter comprising a'channeled blade holder, ablade'removably insertable into said channel, and. a' beveled insertcarried in the channel and partially blocking an end thereof, saidinsert being configured to provide an undercut recess thereunder, intowhich recess an end of the blade may be inserted.

3.A pile wire cutter comprising a channeled blade holder, and awedge-shaped insert carried in one end of the channel, said inserthaving its underside angularly disposed with respect to the channelbottom.

4:. A pile wire cutter comprising a U-shaped blade holder, and an insertcarried in one end thereof and so disposed as to block the open portionof the U, the insert being so dimensioned as to be insertible throughthe open top of the U whereby a recess is provided under the insert intowhich an end of a blade may be inserted.

5. A pile wire cutter comprising a U-shaped blade-receiving channel, ablade removably insertable thereinto, an insert within the channel andproviding a raised bottom therefrom upon which the blade may be made torest, and an insert carried in one end of the channel and configured toprovide an undercut recess into which an end of the length to engage oneend of the blade and 1 a portion cut up from a wall of the channel toengage the opposite end of the blade.

7 A pile wire knife comprising, in combination, a blade holderpresenting a groove in which said blade is received, and insert meansreceived in said groove to provide a raised bottom for the groove and onwhich the blade can be received and an abutment to overhang one end ofsaid blade.

In witness whereof, I have signed this specification.
